After watching the ADB video, I had to do it differently, as I don't have a Y, or a berg connector. These are the jumper settings I used - the cloning process is able to be run solely over the 50-pin SCSI cable, using the SE PSU, or external PSU: PWR-ON=closed, TRM_PWR=closed, both Initiator...

An older friend from work just gave me his SE M5011, apparently he has no attachment to it, and didn't want to deal with selling it. I had told him of my recent success of an SE M5010 restoration, and of another work in progress with a fussy SE/30. So he figured I could use some more old Mac...

Thanks for the help, the PDS slot is much easier to measure. I'll go over all this thoroughly this weekend. I gave that pinout a try, and there is still no answer from either the SE or SE/30. With TeraTerm setup like the ADB video: Can't believe how difficult this has been for some reason...

Will check it out.

Which address lines are you suggesting I should measure? Thanks.

Will dig out the scope today, it's buried good, but really wanted this cable to work.

I have a working SE, that is also not answering to the commands shown in the video. *A - for ASCII mode *5 - to run the test *R - No response from the SE or SE/30. I'm now wondering if my DB9 was wired backwards, because I'm using a female connector, and the diagram shows the male pinout...

Making this Tech Step cable has not been easy, still not getting a connection from either the SE or SE/30. As verified with a continuity test. DB9 = Din-8 pin color 4. DTR = 1. Black 8. CTS = 2. Brown 3. TXD = 3. Red 5. GND = 4. Orange 2. RXD = 5. Yellow 7. RTS = 6. Green 1. DCD = 7. Blue 6...

Amazon delivered me an open-envelope today, that was empty, my DIN 8-pin cable is floating around in the back of an Amazon truck - somewhere. The replacement cable will be here tomorrow, was hoping to get this going today.

Going to try this:

Thanks for that, but they want $14 shipping, or about $40 total for that cable - that I may use this one time only. But I should be able to make any RS-232 COM cable I need now, with all of those adapters and ends I've bought, thinking my cable had all of the wires inside. The 8-wire cable...

This is exactly what the problem was, this is a 5-wire cable with 8-pin and DB9 connectors. Ordered an 8-wire cable this time, should be here tomorrow. https://www.amazon.com/gp/product/B0D415MLGV

That's a good idea, to check my current cabling with the working SE. Might as well do that, just to be certain the cables work, will do. I did recently complete the restoration of a C128/1571 drive over at lemon64; I got bit by the Commodore bug again when a generous and really cool older...

This is a good sub. https://www.mouser.com/ProductDetail/232-XK680MEFCSN35X40 Took that from the parts list maintained by JDW, it's always up to date: https://docs.google.com/spreadsheets/d/18X-EN67lQdZ2crCBAlkHrtqCCoJK6cLw_BkIYdlJvgs/edit?gid=0#gid=0

I do have that SE, it's like new, but don't have the straight 8-pin cable. But the cables I have should work, have the 8-pin to DB9 on the left, DB9 Null modem cable just in case the Rx Tx isn't crossed, and then this USB COM port, that was used in the past with Cisco RJ-45 COM ports. In the...

Got everything hooked up correctly, and still no Terminal access, got the CR+LF and Echo working properly, could see the commands given, but am not getting any response from the SE/30 board. This would mean the CPU, the Serial controller, or the Glue chip is not working correctly. Going to...

This particular cable said RS-232, but no mention of Null output. The adapter will be here tomorrow finally.

It took forever to get that din-8 to DB9 cable from ebay. When I connect it between a PC/USB COM port and the SE/30 serial port next to the audio output jack, I get no flashing cursor or keyboard input in Putty or TeraTerm, both set to 9600, 8, 2 stop bits, no parity, no flow control. Have a...

I've got to try to fix this stock board, if all else fails the Reloaded board is a great option. Gives me some hope this can be a useful tool. Thanks.

Nice work! What are you using on the DB9 end to talk to the SE/30 board with? Have you been able to retrieve any useful info from it?
